Without learning editing, without spending any money, and without using any paid software,

you can create thumbnails just like anyone else. Shall I show you some magic? Yes, let’s begin!

You can still create thumbnails just like popular creators such as Dhruv Rathee, Fukra Insaan, Pragati Verma, Tech Burner, or anyone else.

In fact, you can even make thumbnails better than theirs.

Free thumbnail maker

There are many free thumbnail makers present on the internet that may give you the proper thumbnail for your YouTube videos.

Maximum of them are paid software and after a particular period of time you need to pay for subscription mode.

First, download the thumbnail of the creator whose style you want to copy from YouTube.

Next, go to free ChatGPT. For example, suppose I take a thumbnail from Jothan Gaming. Upload it by simple drag-and-drop. Then, just type:

“Give me the exact prompt for this thumbnail.”

ChatGPT will instantly generate a detailed YouTube thumbnail generator AI prompt describing every single element.

For example —text, colours, graphics, style, everything from A to Z.

Copy that prompt and paste it into Ideogram, which is also free.

Here, you can customise whatever you want—change the text, colours, or theme.

For example, instead of Crate Opening, I can replace it with my own name, Kamalpreet.

Click Generate—and within a few seconds, you will get four amazing thumbnails for free!

If by mistake the thumbnails appear in a 1:1 ratio, don’t worry. You can simply change the ratio to:

• 9:16 for Reels/Shorts cover
• 16:9 for YouTube

Click Generate again, and you will have four perfect thumbnails ready.

Because of this easy process, even beginners can now learn how to make a free thumbnail for YouTube without professional skills.

It answers the common question: “How do I create a thumbnail for YouTube?” perfectly.

How to face swap or change in YouTube thumbnail

If you are running a faceless channel, you can stop here.

But if you want to add your own face (which usually works better), here’s what you do:

Upload your generated thumbnail back to ChatGPT, along with a clear picture of your face.

Simply type: “Replace the face in the first image with the face from the second image.”

Within a minute, your new thumbnail will be ready—your face perfectly blended with the design, polished and professional.

This step is important because what makes a good thumbnail for YouTube is the personal connection.

Your audience relates to your face and expressions, and AI thumbnail maker tools allow you to achieve this without Photoshop.

Much like professional editors, this combination of ChatGPT + Ideogram is in conjunction with modern AI workflows.

Accordingly, you no longer need to wonder “How does YouTube generate thumbnails?”

or “How do I make YouTube thumbnails?” because now you have the control.

Conclusion

Please don’t directly take someone else’s thumbnail and just replace their face with yours—that’s not ethical.

Instead, always use ChatGPT to generate the prompt first, and then create your unique version in Ideogram.

With one account, you can create 4–5 free thumbnails per day.

If you use 2–3 accounts, you can easily generate 10–12 thumbnails daily, which is more than enough.

You can even offer client work this way.

So, this is the simplest and most effective method to make professional-level thumbnails without spending a single rupee.
